# HCP Packer Iteration ID
~> **Note**: Deprecation: Contextual Variable `iterationID` has been deprecated packer context. Please use `versionFingerprint` variable instead.
~> **Note**: The `packer.iterationID` variable is now deprecated and will be removed in a future version of Packer. HCP Packer Versions should be accessed with their fingerprint instead. The `packer.versionFingerprint` variable is now exposed to be used in its stead with the new HCP Packer data sources.
If your build is pushing metadata to the HCP Packer registry, this variable is
set to the value of the Iteration ID associated with this run.
